zcn of the United States, r siding at Buffalo,

in the county of Eric and State of New York, lr-ue invented a new and useful Improvement in Spring-Lid Boxes, of which the fol lowing is n specification.

This invention relates to boxes or cases of that class having url'ntch l'orholding the cover closed and n spring for automatically throwing the cover to its open position when released. i

One of the objects or my invention is to simplify the construction and reduce the cost of the catch and the spring. A further object is to so combine the catch and the spring that the releasing movement, of the cntc-ll increases the stillness of the spring while the closing of the cover st-itlens g catch, causingit to. more securely lock the cover. i

In the accompanying drawings: Figure 1 is a perspective view-0f. a jewelry hox embodyin; the invention-with the cover open, the pu l or cushion being omitted. Fig; 2 is a cross section thereof witn the cover in the same position and the purl in place, and showing the position of the spring catch when pressed and about to return to its locking position. Fig. 3 is a similar section with the cover closed. Fig. 4 is a cro s section of a modified construction of the box with the corcrclosvd and the pad omitted.

In the preferred construction shown in the one piece with the bar E and said catch. It extends upwardly from the rear and of the bill to 1 poin above the hinge ol' the cover arranged to bear againstthe rear wall of the cover when thehitter is closed. By this construction, upon closing the cover, the spring is dellccterl lorwnrdly, as shown in Fig. 3, and upon pressing thebutton d" to unlock the cover, the spring reacts and throws the latter open..-

as a stop to limit the opening movement of the cover. .For this purpose, the swing is proiided at its upper and with it hook g which engages behind 'a lip or tongue h on the and, 2;

- The her E which carries the catch (1 and the )ring 9 is preferably cupnble of sliding lengtl I formed by the lips f, the ba lacing of the proper length to permit of such longitudinal ony. By this construction, when the spring cntrh 1 )lesserl inward to rrlease the cover the "our j; is shil'tml rezrrwsrdly, increasing the stillness or resilieru'zc of the spring and improving its action. while when the cover is closed the resultant pressureagainst the spring causes the hair E to be shifted forwardly, increasing the stillness of the spring catch "Z in like in nincr and causing it to more reliably interlock with the cover. ciprocnl stiii'cning notion of Lhe spring-catch and the cover-owning spring is obtained hv 1 the simple orpodicntof connecting the catch and the spring hy a bar or carrier which is free to slide back and forth to the necessary extent. A1 the'samo time, the. integral construction of the catch u'nrl the spring materielly reduces the oost of these parts and inrilitatcs their attachment to the box.

box. The spring also does not interfere to an objectionable extent with the usual neck J of the box, and as it is stifl'ened in the act of releasing the cover, it may be formed with less curve or bulge than could be the case if this feature were absent, thus correspondin ly reducing the extent to which the spring inr ents the neck. The lips while permit ting the bar E to slide lengt iwise, as above described, prevent it from rocking on the bottom of the box, thus effectually holding the 5 )ring catch as well as the spring from disp acemcnt.

If desired, the stop-tongue h and stophook g may be omitted, as shown in Fig. 4.

It is obvious that the spring 9 can be made longer or shorter to cause-it to open the cover to a greater or less extent or at different an les to the body of the box.

he improvement is herein shown inconnection with a jewelry box, but it may obviously be applied to other boxes of various kinds.

I claim as my invention:

1. In a box, the combination of a body, a hinged cover, a bar arranged within the body and resting upon the bottom thereof, said bar being rovided at its front end with a. spring-eaten adapted to interlock with the cover and at its rear end with an openingspring arranged to act against the cover, and means for attaching'said bar to the bottom of the box-body, substantially as set forth.

2. In a box, thelcombinat-ion of the body,

a hinged cover, and a bar extending along the bottom of the body and having its front end bent upward to form a spring catch adapted to interlock with the cover and having its rear end bent upward to form a cover-opening spring, the bottom of the body having retaining iips which overlap said bar, substantially as set forth.

3. In a box, the combination of the body, a' hinged cover rovided on the inner side of its rear wall wit a stop, a bar secured to the bottom of the body and having its front end bent upward to form a spring-catch adapted to interlock with the front portion of the cover and having its rear end bent upward to form a cover-o cning spring, said spring terminating in a ook arranged to engage the cover-stop, substantiall as set forth.

4. In a box, the com ination of the body provided in its bottom with guides, a hinged cover, and a sliding bar resting on the bottom of the body and arranged in said guides,

said bar bein provided at its front end with a spring-catch adapted to interlock with the cover and at its rear end with a cover-openin spring which bears against the cover, substantially as set forth.

Witness my hand this 25th day of October, 1906.
